PSR Sulfur Recovery Catalyst is used to treat with the acid gases containing H2S for the sake of recovery sulfur element and environmental protection in oil refinery, chemical factory, Iron & steel plant and natural gas treatment processes. The conversion of sulfur can reach to 65~75% in a ordinary bumer, 92~95% it react by two stages Clause processes, furthermore to higher than 98% if by three Clause reactors.
